  • METHOD AND APPARATUS FOR MEASURING RAMAN SPECTRUM
    Publication number: 20180252649
    Abstract: An apparatus (500) for Raman spectroscopy includes: a laser unit (200) to form laser pulses (LB1), a conversion unit (100) to form illuminating pulses (LB3) from optical energy of the laser pulses (LB1), optics (LNS1) to gather scattered light (LB4) from a sample (MX) when the sample (MX) is illuminated with the illuminating pulses (LB3), a spectral disperser (350) to spatially separate spectral components (LB4?1, LB4?2, LB4?k, LB4?N) of the scattered light (LB4), a detector array (ARR1) to measure intensity of the separated spectral components (LB4?1, LB4?2, LB4?k, LB4?N), wherein the conversion unit (100) includes: a first crystal (NLC1) to generate second light pulses (LB2) from the laser pulses (LB1) by second harmonic generation, a second crystal (RaC1) to generate the illuminating pulses (LB3) from the second light pulses (LB2) by stimulated Raman scattering.
